SPECIFICATION forming part of Letters Patent No. 297,947, dated April 29, 1884.

Application filed December 20, 1883. (No model.)

.To all whom it may concern:

Be it known that I, JAMES N YOE, a citizen of the United States of America, residing at Deckertown, in the county of Sussex and State of New Jersey, have inventedcertain new and useful Improvements in Tire-Upsetters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such ,as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in attachments for anvils, its object being to provide an attachment which can be readily secured to anvils for the purpose of upsetting tires, so that said operation may be performed by a single person without assistance; and my invention consists in the construction and combination of the parts, as will be hereinafter more fully set forth, and pointed out in the claims.

In the accompanying drawings, which illustrate my invention, Figure 1 is a perspective view. Fig. 2 is a sectional view, and Fig. 3 a detailed View.

A represents an anvil, which is mounted upon a block or base in the usual manner, and is of ordinary construction, and is provided in its body or web on the side opposite the horn with a perforation, a.

B represents a plate which is of sufficient width to extend beyond the sides of the face of the anvil, which portion is provided with a recess, 22, for the reception of a serrated plate or swage, b, which has its end turned down, as shown in Fig. 1. This plate Bhas formed on its lower side a downwardly-projecting portion, a, which is rectangular in cross-section, and will fit snugly into the hardy-hole in the anvil, and it is also provided with rearwardly and downwardly projecting members 0, the lower portion of saidmembers projecting inwardly parallel with the upper portion, as shown. vided near its edges with openings or perforations d, and the lower portions vertically under these :perforations are also provided The plate B is proa with perforations (1. The upper portions of the members 0, near their downwardly or vertically bent portions, are ,provided'with upwardly-projecting pins 6, upon which are secured collars or washers 6. Over these upwardly-projecting pins are placed two holders, 'D D, which are provided at their rear ends with downwardly-bent portions and perforations, through which the pins 6 may pass. At a suitable point these holding-plates D have securely attached thereto downwardlyprojecting bolts or rods E, which pass through the perforations d d, hereinbefore referred to. These bolts at a suitable point are provided with keys and washers f, under which is placed a spiral spring, which will rest upon the members 0 adjacent to the perforations cl. The lowerends of these rods are screw-threaded and provided with nuts. Over these rods and above the nut is placedan arched bar, G, having a central eye, in which eye is secured a link or hook, h.

In theperforation a in the body or web of the anvil is secured an eye, 2, in which a bar having a hook formed on its end engages. This baris also provided with a perforation, in which the link or hook his attached. At the end -of this bar, which is indicated by the letter I, is an opening for the reception of the link 70, which is attached to the footlever K, one end of which is pivoted to the eye secured in the anvil-bed.

Then it is desired to secure the anvil more rigidly in place,'a bent bar, L, as shown in Fig. 3, may be passed over the horn, so as to rest adjacent to the face of the anvil, the lower end/being passed through an eye in the anvilbed. B ythis means the anvil will be prevented from tilting when pressure is placed upon the lever K, though in some cases this additional security will not be needed.

I am aware that prior to my invention attachments for anvils for upsetting tires have been provided, as shown in Patent No. 92,881, dated July 20, 1869, and No. 251,964, dated January 3, 1882, and in view of these patents a further description of my invention is unnecessary, the operation of my invention being obvious.

From the constructlon of my inventlon,

more especially in providing the holding-bars D with two guides in rear of the swage, a lateral movement of said holding-bars is prevented, and by having the ends of these holding-bars bent when the same are drawn downward the pressure will be thrown upon their forward ends, so as to hold the tire securely in position. Moreover, this invention can be applied to an anvil of ordinary construction, by providing the vertical bars with springs which act substantially directly upon the holding-bars, the same will be thrown upward, so as to release the tire when desired. Moreover, by making the bed-piece B of a single piece, as shown, an open face is provided in front and to the rear of the bulge in the tire, so that it can be readily operated upon, the parts of my improved attachment being such as not to interfere.

Having thus described my inventiomwhat I claim as new, and desire to secure by Letters Patent, is-

1. The improved attachment for anvils, consisting of the bed B, made of a single piece, and having members 0 formed thereon, in combination with the holders D, having bent ends, and means for depressing the same upon the bed-piece, substantially as shown, and for the purpose set forth.

2. In an attachmentfor anvils, the bed-piece B, provided with members G, perforations d d, and upwardly-proiecting pins 0, in combination with the holders D, having their rear ends bent, as shown, and provided with downwardly-projecting bars E, with spring elevating means, and a cross-bar, G, attached to each of the bars, and provided with means for depressing the same, the parts being organized substantially as shown and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES NYOE.
